Question

Difficulty: MediumSubject-Verb Agreement (Concord)

Provide the grammatically correct verb form to complete the sentence with appropriate subject-verb agreement.

Answer:The lead architect and project designer 【has】 submitted the final blueprints for approval.

Answer

has
The subject 'The lead architect and project designer' refers to one single person who holds both titles, as indicated by the single article 'the'. Consequently, the singular auxiliary verb 'has' must be used for correct grammatical concord.

Step-by-Step Solution

1
Identify the subject of the sentence and determine its grammatical number.
The subject is 'The lead architect and project designer'.
The singular definite article 'The' is placed only before the first noun ('lead architect'), indicating that both titles refer to a single individual performing both roles.
2
Apply the subject-verb agreement rule for compound subjects designating a single entity.
A singular subject requires a singular auxiliary verb.
Since the subject represents one person, the singular auxiliary verb 'has' is required to complete the present perfect verb phrase 'has submitted'.
